Problems solved by technology

One of the main drawbacks of this method is that there is great randomness in the dripping process of the molten liquid formed during the combustion process of the thermoplastic plate wall, the dripping rate of the molten liquid is uncontrollable, and the development and spread of the liquid below the oil pool The process is mainly determined by the dripping rate of the molten liquid, therefore, existing methods limit the in-depth quantitative analysis of the development and spread characteristics of molten liquid oil pool fire in thermoplastic materials

Embodiment 1

[0031] figure 1 A schematic diagram of the overall structure of the thermoplastic material heating, melting, dripping and burning test device with inert gas protection is given, figure 2 An enlarged view of the bottom opening and stopper of the metal container of the device, image 3 It is a top view of the multi-branch tank. In this embodiment, the thermoplastic material heating, melting, dripping and burning test device with inert gas protection is placed under a fume collection hood with a smoke exhaust fan, so that the pyrolysis products in the metal container and the combustion fume from the oil pan at the bottom can pass through the fume collection The hood vents to the outside.

[0032] Such as figure 1 As shown, a stainless steel metal container 1 with a conical bottom is placed in an electric heating furnace 2 . For example: the bottom and side walls of the metal container 1 are heated by the electric heating wires of the electric heating furnace 2, and the electri...

Abstract

The invention provides an inert gas-protected thermoplastic material heating, melting, dripping and combusting test device. The inert gas-protected thermoplastic material heating, melting, dripping and combusting test device comprises a metal container (1) with a small circular hole at the bottom, wherein the metal container (1) is put inside an electric heating furnace (2); a small circular hole is also formed at the bottom of the electric heating furnace (2); and central axes of both the small circular hole of the metal container (1) and the small circular hole of the electric heating furnace (2) are aligned with each other in the vertical direction. In the combusting process, polymers, particularly a thermoplastic material, easily drip combustible molten liquid to form flowing fire; by heating such polymers, controllable melting dripping mass rates can be achieved; and through nitrogen gas protection in the heating furnace, in the heating process, the polymers can not be combusted, so that flowing combustion behaviors of the various polymers under the conditions of different melting dripping mass rates can be quantitatively studied.

Description

technical field [0001] The invention relates to the field of thermal behavior and flowing combustion characteristics of polymer materials, and more specifically relates to a thermoplastic material heating, melting, dripping and burning test device with inert gas protection. Background technique [0002] The development and wide application of synthetic plastic technology has brought many conveniences to people's production and life. However, the flammability of these materials will often increase the fire load in the space, which will easily bring new problems in fire prevention and control. Among them, thermoplastic materials (such as polyethylene, polypropylene, polystyrene, etc.) are widely used in automobiles, aviation, home appliances, offices, interior decoration, etc. Decoration and other occasions have been widely used. After this kind of thermoplastic material and its products are ignited, molten liquid combustibles will drop downward during the combustion process...
